First and Goal Water Cycle: Pairs of students answer questions about water and its properties. When players answer questions correctly, they move game pieces across a football field board in an attempt to either make a touchdown, or to block the quarterback.

First Pick Planets: In this fast-paced game, small groups of students rush to trade their cards in order to collect the sun and all the planets. The first student to put down all the planets in their order in relation to the Sun wins the game.

I Have Who Has Landforms: Large groups of students listen to each other ask questions about landforms and forces that change the land and respond in turn with matching shapes, while trying to put the cards in order. Time your group to see how fast they can do it. Then do it again to see if the time improved. After you play the game, put these cards in a center for individuals or small groups to sequence on their own by stacking them on top of each other.
